Moreover, different wavelengths of light have different effects on plant photosynthesis. Generally, the wavelength of light required by plants is around 400-720nm, of which 400-520nm (blue) light and 610-720nm (red) contribute to photosynthesis. The traditional light supplement technology does not take into account the differences in the amount and color of light required by different plants and different growth stages of plants, resulting in insufficient light supplement, excessive light supplement, inaccurate light supplement, and serious energy waste.
